The title compound, [Ni(C2H5NO2)2(H2O)], is a mononuclear nickel(II) complex. The NiII atom is five-coordinated by two N atoms and two O atoms from two glycinate ligands in basal plane positions, and by one O atom from a coordinated water molecule in the apical position, forming a slightly distorted square-pyramidal geometry. In the crystal structure, molecules are linked through intermolecular N—H...O and O—H...O hydrogen bonds, forming a three-dimensional network.

In the title compound, [Cu2(OH)2{C12H7N2(PO3C2H5)}2(H2O)2]·7H2O, two Cu2+cations are bridged by two hydroxide groups, forming a centrosymmetric binuclear complex. Each Cu2+cation is further coordinated by the N atoms of a bidentate ethyl (1,10-phenanthrolin-3-yl)phosphonate anion and a water molecule in a square-pyramidal geometry. In the crystal, a network of O—H...O hydrogen bonds involving the P(O)(O−)(OEt) groups, bridging hydroxyl groups, coordinated and uncoordinated water molecules generates a three-dimensional supramolecular structure. The ethyl group exhibits disorder and was modelled over three sites with occupancies of 0.455, 0.384 and 0.161.

The asymmetric unit of the title compound, 2,4,6-triamino-1,3,5-triazin-1-ium cyanoacetate monohydrate, C3H7N6 +·NCCH2COO−·H2O, consists of a melaminium cation, a cyanoacetate anion and a water molecule, which are connected to each other via N—H...O and O—H...O hydrogen bonds, generating an eight-membered ring. In the crystal, the melaminium cations are connected by two pairs of N—H...N hydrogen bonds, forming tapes along [110]. These tapes develop a three-dimensional network through N—H...O, O—H...O, N—H...N and C—H...O hydrogen bonds between the cations, anions and water molecules.

The crystal structure of the title salt, [Cu(ClO4)(C8H20N4)]ClO4, is reported. The CuIIion exhibits a square-pyramidal geometry and is coordinated by the four N atoms of the neutral 1,4,7,10-tetraazacyclododecane (cyclen) ligand and an O atom from one perchlorate anion, with the second perchlorate ion hydrogen-bonded to one of the amine N atoms of the cyclen ligand. Additional N—H...O hydrogen bonds between the amine H atoms and the coordinating and non-coordinating perchlorate groups create a three-dimensional network structure. Crystals were grown from a concentrated methanol solution at ambient temperature, resulting in no co-crystallization of solvent.

In the title compound, [Cu2(C2H4NO2)2(C10H6O6S2)(H2O)6], the naphthalenedisulfonate group lies on a center of inversion and bridges two glycinate-chelated CuII atoms. The CuII atom exists in a CuNO4 square-pyramidal geometry that is distorted towards an octahedron owing to a long Cu—Osulfonate bond [2.636 (2) Å]. In the crystal, extensive N—H...O and O—H...O hydrogen bonds link adjacent molecules into a three-dimensional network
